According to the valve type opening and closing hysteroscope, before examination or operation, when an opening and closing valve is in a closed state and reaches an examination position or an operation position, the opening and closing valve is opened through an opening and closing handle, the opening and closing valve can open the examination position or the operation position, and examination or operation is conducted through a micropore camera on an imaging seat; when tissue fluid or blood blocks an examination position or an operation position, the flushing fluid assembly pumps flushing fluid into the examination position or the operation position, after flushing, the vacuum extraction assembly is started to suck away mixed fluid of the tissue fluid or the blood and the flushing fluid through the negative pressure suction hole, and after examination or operation is completed, the opening and closing valve is closed through the opening and closing handle, and the flushing fluid or the flushing fluid is pumped into the examination position or the operation position. In this way, the problem that tissue fluid or blood flowing out of the human body blocks the view field of the hysteroscope can be effectively solved, and when the opening and closing valve is closed, the imaging assembly is in a streamline shape and can conveniently stretch into the hysteroscope for examination or operation.

Description

Technical Field

[0001] The invention relates to the field of medical equipment, and in particular to a flap-type opening and closing hysteroscope. Background Art

[0002] Hysteroscope is a light source hysteroscope mainly used for intrauterine examination and treatment. It uses the front part of the scope to enter the uterine cavity, and is the preferred examination method for gynecological hemorrhagic diseases and intrauterine lesions with intuitiveness and accuracy. However, in the prior art, when examining the patient's uterus, it is usually necessary to first insert the hysteroscope from the patient's body into the uterus to observe the patient. When the lesion is found, the hysteroscope is taken out to treat the patient, or the hysteroscope is kept in the patient's body and a treatment device is inserted into the patient's body at the same time to treat the patient.
